earns-e edit on es iEEGIIFIGATION is formed with an annular depression to re ceive the hearingfaces of the roller.

Referring to the drawings letter (Z repre-- sents theshait. On this shaft is mounted a cage composed of end pieces 17 provided with apertures toreceive'the shaft, the end pie'ces being connected by cross bars 0 laid in radial slots, substantially as shown in Fig, 2 of the drawin'gs. Intermediate-with the cross bars 0 are formed radial slots 0; in which are disposed small journals projected from the ends of the anti-friction rollers h. This cage is mounted or arranged upon a shaft d and the rollers are arranged thereon with journals disposed in the open-end radial slots i substantially as shown in the drawings. Arranged over the cageis a cylindrical casing e tapering lengthwise upon its exterior surface substantially as shown in Fig.3 of the drawtags, and is slitted diagonally, as shown at Z in order that it may be contracted to take up the wear of the rollers. This casing e is arranged. over the cage and rollers substantially as shown in Figs. 1 and 4.

lhc letter f designates a. cup-shaped casing having, a threaded exterior surface as shown in the drawings, and a flaringinterior surface to tit over the tapering exterior of the casing e as showh in Fig. 4. This casingf fits snugly and firuilyI 'np'on the casing e in order that in the adjustments to be made, the casing 6 may be contracted to take up the exigencies of the rollerswhich may arise by the continued operation of the device.

(Bio modah) open-end shell having interior threads to 'engage the casing f, and is provided-wither? j usting screws 9 let through the end face and engaging against the edge of the interior split casing e as shown in Fig. l of-the draw ings.

.To prevent the endwise movement of the rollers on the shaft, the shaft may be formedwith an annular recess as shown in Fig. 4,

wherein the rollers turn. The shoulders'of these recesses are preferably made slightly tapering and the ends of the rollers are the Y pered to conform, to the shape of the walls of the annular recess.

In Fig. 4 the casing to is formed with an upper edgesof the respective rollers; and the casingf is formed with a similar flange k. to

serve the same purpose at the opposite end of the roller. Through the casiuga' are projected a requisite number of adjusting screws 9 bearing with their ends against the end face of the casing 6, whereby turning these adj usting screws the casing 6, may be forced into the casing f and the casing c-thus contracted and the rollers hold in connection of operative position within the cage, and in contact with the shaftthuscompensating for,or taking up any wear that may have been occasioned by the use of the device. 1

Having thus described my invention, what I claim and desire to, secure by Letters Pat out is exterior-annular flange j projectirigfromits. inner end face to contact with the outer or 1. The combination of the shaft, a'cage arranged thereon, havingfend pieces connected by cross bars 0, and intermediate bearingsbetween the cross bars in the and pieces, ant-ifriction rollers mounted'in the bearings of the cage, a casing e diagonally split and haw log a, tapering exterior surface arranged over the cage and rollers, acasi'ng having threaded exterior surface and a flaring interior ,to set over-the tapering exterior of the casing e, and an exterior casing having interior threads to engage the exterior threads of the casing and engaging the end of the split casing e, where by the wear of the-rollers may be compensated or taken up, substantially as described.

2. A roller bearing composed of the hhaft d formed'with an annular-recess, as shown, a. I cage mountedo'n the shaft, composed of end Q 46am? cage, the split cylindrfciil ring ehavinga tai paring outer surface a casing f having. a.

threaded exteriqr, and an interior flaring surface to set over thempering surface of the split easinge and formed with an-inter ioranr nuiarvflange k to set against the end of theto anti friction 'rollei s; and the outer 0asing' a 7 formed with interior thraads to engage the casing f, and a proiecting interio': annular",

flange to set; against the ends of. the anti frictionmliers; substantially as andifor the par-' pose spcified.
